[Rd] about R CMD check

[xt_wang at cse.concordia.ca]

hello,

I create a package which includes C code and Lapack. But when I run " R CMD
check ". an error message, "/usr/bin/ld: cannot find -lfrtbegin " occurs. could
you tell me what is the problem?

the detailed message is as follows:
[credsim at confsys ~/src]$ R CMD check var
* checking for working latex ... OK
* using log directory '/home/credsim/src/var.Rcheck'
* checking for file 'var/DESCRIPTION' ... OK
* checking if this is a source package ... OK

* Installing *source* package 'WXT' ...
